Timeline
6G research is picking up with several
initiatives such as the Hexa-X European
6G flagship project with Nokia acting as
the overall lead, Next G Alliance in the US
, China’s IMT-2030 (6G) Promotion Group,
Beyond 5G Consortium in Japan, and
the Korean government’s (MSIT) 6G R&D
implementation plan.

6G Standardization is estimated to start
by 2024/2025-time frame, with first
3GPP 6G Specifications to be ready by
2028, and first deployments starting by
2029/20230. 6G success depends on
global unified approach where we need to
bring in harmony different regulatory and
standardization efforts and timelines.

in the future beyond 2030. The rapid
advance of AI/ML technology and its
effectiveness in solving problems in several
domains points toward a 6G system that
will fundamentally exploit these new
capabilities to improve performance by
better adapting to the operational
environment. The insatiable demand for
higher capacity and peak rates points
toward technologies that will exploit
existing and new spectrum bands. As the
density of infrastructure increases, coupled
with the use of wider bandwidth signals,
especially indoors, new opportunities to
utilize this for localization and sensing will
encourage a 6G design that is not only
optimized for communication but also for
perception and understanding of the
physical world and people’s needs, thus
augmenting human existence in the most
